Single-stage compressors have one piston that compresses and delivers air to the storage tank. They are suitable for most home users. Two-stage compressors have two pistons that compress and deliver air to the tank. These can store more air in the same space as a single-stage and are much better for commercial uses and shop environments.

Stationary compressors are designed to be bolted in a fixed area and wired directly to a building's electrical circuit, these are ideal for garages and workshops. Portable air compressors are perfect for jobs that require use of air tools like nail guns frequently, such as re-siding your home or building a deck. Pancake compressors are smaller and very easily portable, they're great for inflating and running small tools. Twin tank compressors can store more air so they don't have to run as often.

Electric-powered compressors are most common and easiest to use in areas with a ready electric supply. Gas-powered compressors are a good choice in areas where electricity is limited or unavailable, but they should not be used in confined or unventilated areas.
